  1. One of my questions was if the A/T worked in reverse....he said no. There is no solenoid activated for reverse....as I stated, R is strictly hydro-mechanical in nature. Therefore diagnosis proceds as determining what component is activated in all gears 1-2-3-OD and reverse. CO (forward clutch) is active in every gear but o/d. If the car won't go 40mph you cant get to OD. Simply removing soleniod wires will activate a trany in limp in mode...2nd gear starts (sluggish but no slip) and a crisp up shift to 4th when 3rd would normaly come in. This is a valid check for forward, direct and O/D clutch packs. BTW, Last friday I replaced a tranny with less than 12,000 miles on it with a direct clutch pack that was so overheated from slipping the multidisc pack was fused together. They are good, not perfect. I bet you would be hard pressed to find a 97-98 Rav 4 with an OEM tranny in it. Diferential spyder gear washers exploding, and because of filter design it got pumped everywhere and we lost forward and direct pacs.
  2. click on my member name and my email is avaliable....MKBeyer*nospam-*@aol.com remove the *nospam-* I am editing you post ifixem to add the words *nospam* Other wise searchengines can find your email and add you to a list of garbage quite easily. For everyone else please take note. I don;t favour openly adding an email adress but if you do make an easy alteration to make it alittle harder to help spam find you.
  3. Make sure your PCV hose is still conected to the intake, not just the valve, at the right side of the plenum.. Last time you pulled rear plugs you are right next to it and might have bumped it. It's real easy to bump. This will give a return of P0171 ('cuz now it is lean) and you will have missfire % on all 6 cyls...before we only had miss on 1, 3, 5.
  4. I tired to make excuses for the other dealer missing the MAF issue and fuel trim P0171, if they are sticking by O2 sensors to fix a miss, then I would rather you pay $10 to call me for 1/2 hour long distance at work or home than take it back there. You can remove ALL O2 sensors from a car lay them on the bench and start the car...you will get an exhaust leak, O2 sensor performance code, O2 sensor heater ckt code BUT NO MISSFIRE.
  5. I was wrong about the sprag and I thought I might have been. If you have good presure in P and N and then experience presure loss in D and R it is in the forward clutch circuit like I first posted....if you have low presure allways presure reg in valve body, filter, pump etc. No simple fixes here. The box needs to come out and appart. I suspect it is low psi in D and R only and you have either blown out a C0 (forward clutch) accumulator seal or pipe, or had the C0 piston seal fail. Is the tranny pan dented near the front?
  6. Vince, in the shop manual for the 1MZFE (at least in my 2002 but its probably the same of rthe 1999) the trouble areas are listed in an order for each code. Under code P0171 it lists in this order: Air intake (hose loose) Fuel line pressure Injector blackage open or short in A/F sensor circuit A/F sensor malfunction Intake flow meter Rather than test the two items before the AF sensors and then test the AF sensor and then test the MAF sensor as the inspection procedure illustrates, it sounds like the dealer wanted to just "test by replacement" and hope it goes away. I'm guessing on this next one but I think the MAF sensor replacement is overall less expensive so they go with the mose profitable.?. steviej ← Sorry, I have spoke to soon. The problem has come back. Both the CEL and the Track off light have illuminated and the engine has begun to run a little rough. I have also noticed that the catalyic converter is getting real hot, reason being that it is pinging when I shut down the car. I have the print outs from the diaganostic machine from lexus, but cannot make out what it really means? It has percentages next to each cylinder 1-6 with the error codes. But Inskip Lexus insisted that it was the O2 sensor? Question#1 Can all the experts here on the forum reevaluate this problem? Thanks Much Vince ← Vince, Missfire is caused by compression loss, coils, wires, plugs, cam timing... 20 years, never seen an O2 sensor cause missfire. What are the % next to each cyl? I think you need to pull all 6 plugs and wires and check plugs for hairline carbontracks....looks like pencil lead down the porcilin. Spray some of your leftover brake clean down each plug bore to remove any moisture traces. Ohm check plugwires when they are out...8-15Kohms is nominal. Does your printout give a reading next to cal load? what about MAF g/sec? injector M/sec? post these if it is on there along with short term fuel trim. We can get this. I think you fixed 1 problem but are still looking at missfire caused by water intrusion that has carbon tracked a plug or two. Look/listen for vac leaks hoses off at right side of the plenum.
  7. To think I could have saved $4800....300+ HP for $99 or something right? STOP the MADNESS! ← For Sale.... increase your lawnmower output by 50%...looks like a hairdryer, requiers owner supplied 100' electrical extension cord and duct tape....Only $199.95....ping me for details and dyno sheets.
